Although the zoo’s director, Mohamed Sultan, insisted his zebras were 100 percent legit to local radio station Nogoum FM,a local vet told the Cairo-based ExtraNews.TV that a zebra’s snout should be black and the stripes should be more consistent and parallel, according to the BBC.

CBS News also notes that zebras and donkeys, despite both bearing a resemblance to horses, are different species.

Other zoos have also been accused of trying to gray the area between zebras and donkeys.
